This paper presents the METAXPath data model and query language. METAXPath extends XPath with support for XML metadata. XPath is a specification language for locations in an XML document. It serves as the basis for XML query languages like XSLT and the XML Query Algebra. The METAXPath data model is a nested XPath tree. Each level of metadata induces a new level of nesting. The data model separa...

Complex organization is found in many biological systems. For example, biopolymers could possess very hierarchic structure, which provides their functional peculiarity. Understating such complex organization allows to describe biological phenomena and predict molecule functions. Besides, we can try to characterize the specific phenomenon by some probabilistic quantities (variances, means, etc),...

Phase change materials combine a pronounced contrast in resistivity and reflectivity between their disordered amorphous and ordered crystalline state with very fast crystallization kinetics. Typical phase-change alloys are composed out of the elements germanium, antimony and tellurium. Due to the exceptional combination of properties phase-change materials find already broad application in non-...

A current challenge in system biology is to infer the regulation network of a family of pgenes from a n-sample of microarrays, with n (much) smaller than p. Gaussian graphicalmodels are simple models to describe these regulation networks. We propose a procedurethat performs Gaussian graph estimation by model selection. We introduce a collection ofcandidate graphs and then select...
